Description

TECHNICAL FIELD The present invention relates to an apparatus for peeling a cover tape from a carrier tape body of an electronic component carrier tape.

2. Description of the Related Art Carrier tapes are used as one means for packaging chip-shaped electronic components. This comprises a carrier tape main body having electronic component accommodating recesses formed at regular intervals in the longitudinal direction, and a cover tape bonded to the main body to close the opening of the electronic component accommodating recess, Each recess holds one electronic component. As the carrier tape body, a number of through holes are formed at equal intervals in the longitudinal direction and a thin tape is attached to the back side of a cardboard tape, or a composite of a plurality of small box-shaped parts formed continuously. Generally, a resin film or the like is used, but in any case, each electronic component accommodating recess is formed as a dent with one surface open,
After the electronic components are housed in the recess, the opening is closed by the cover tape, and the large number and the electronic components are packaged in a small space which is independent of each other.

When the electronic components packaged in this way are used, the cover tape is peeled off from the carrier tape body to open the respective electronic component accommodating recesses, and the respective electronic components are taken out. The device used at this time is a cover tape peeling device, one of which is, for example,
As described in Japanese Patent Application Laid-Open No. 9-39999, while the carrier tape is fed in the longitudinal direction in a state where the cover tape is in contact with or close to the back surface of the plate material, the cover tape is pulled out from the slit formed in the plate material to the front side. There is one that is peeled off from the carrier tape body.

By the way, in the cover tape peeling device of this type, as mentioned in the above-mentioned publication, generally, since a plurality of devices of the same type are arranged and used in the width direction perpendicular to the feeding direction of the carrier tape, It is desirable that the width dimension thereof is small, and it is desirable that the carrier tape can be replaced easily and quickly even in the state where a large number thereof are arranged. Further, it is desirable that the cover tape is peeled off with the opening side of the electronic component accommodating concave portion facing upward. Therefore, in the conventional cover tape peeling device, a slit for drawing the cover tape to the front side of the plate material is formed at a right angle to the feeding direction of the carrier tape,
It is usual that the peeled cover tape is folded back to the upstream side of the feeding of the carrier tape in a state of overlapping with the carrier tape in the vertical direction. In this way, the cover tape peeling device can be narrowed by folding the peeled cover tape upstream of the carrier tape feed in the state of overlapping the carrier tape in the vertical direction, and a large number of the cover tape peeling devices are arranged in the width direction. In this case, the installation space can be narrowed, and since the cover tape can be wound on the carrier tape supply side, the adjacent device does not hinder the replacement operation when the carrier tape is replaced, The replacement can be performed easily and quickly.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional cover tape peeling device as described above, when the cover tape is peeled from the carrier tape body, the electronic components adhere to the cover tape due to static electricity, and the electronic components adhere to the slits of the cover tape. The carrier tape is lifted from the electronic component accommodating recess along with the pulling out, and the end of the carrier tape on the downstream side of the feed is caught on the edge of the carrier tape on the downstream side of the carrier tape of both edges of the slit.
As the carrier tape is fed, there is a problem that it bites between the edge of the slit and the carrier tape to cause so-called jamming, which hinders the feeding of the carrier tape and hinders the normal operation of the apparatus. Further, the electronic component floats up from the electronic component accommodating concave portion due to vertical vibration or the like that occurs when the cover tape is peeled from the carrier tape body, and due to the floating up, the electronic component is caught on the opening edge of the slit, and the same problem as described above occurs. It happened.

In order to deal with such a problem, the width of the slit is made sufficiently narrow so that the electronic component does not catch on the slit opening edge even if the electronic component floats up from the electronic component housing recess, or the opening of the electronic component housing recess. The depth of the accommodating recess should be close to the thickness of the electronic component so that the electronic component does not move up and down in the recess for accommodating the electronic component unless it has been opened by a considerable amount. Although it is possible to prevent the electronic components from being caught in the edge of the slit as a state of almost contacting the formed plate material, the former method causes a problem in drawing out the cover tape from the slit, and the latter method. Is not practical as a device that handles various electronic components, so it is difficult to use together.

First Means for Solving Problems The invention of the present application has been made in view of such circumstances, and the gist of the first invention is to cover the electronic component carrier tape as described above. In the tape peeling device, the slit for drawing the cover tape is formed in a plane parallel to the electronic component carrier tape and inclined with respect to the feeding direction thereof.

Functions and Effects of the First Means In this way, if the slit is formed in a plane parallel to the electronic component carrier tape and inclined with respect to the feed direction thereof, the electronic component is provided at the end of the carrier tape on the downstream side of the feed. And one end in the width direction of the carrier tape, that is, the corner portion first faces the slit, and then the portion facing the slit is a corner portion at a diagonal position upstream of the carrier tape feeding as the carrier tape is fed. Will gradually move toward. In this case, it is when the corner of the electronic component first faces the slit that the electronic component may be caught on the opening edge of the slit and cause jamming. At this time, the electronic component is long in the diagonal direction. Since the part is covered with the cover tape, the lift amount of the corner of the electronic component facing the slit is limited to a very small amount, and therefore the corner of the electronic component is caught on the edge of the slit and causes jamming. There is nothing to do. Further, after that, the cover tape is peeled off, so that the opening amount of the electronic component accommodating concave portion is gradually increased. Therefore, the effect of preventing the electronic component from rising by the cover tape is gradually reduced. At the time when the electronic components can float up to the state of contacting the plate material due to the reduction, the corner of the electronic component that first faces the slit passes through the slit and penetrates under the back surface of the plate material on the downstream side of the slit. Therefore, even if a force that lifts the electronic component acts on the electronic component, the floating is prevented by the contact of the corner portion with the back surface of the plate member. That is, according to the cover tape peeling device of the present invention, when the electronic component passes through the slit, the electronic component is not caught on the edge of the slit, and therefore, the jamming of the carrier tape is also avoided. .

Second Means for Solving the Problems Further, the gist of the second invention of the present application is that in a cover tape peeling device similar to the above-mentioned first invention, a slit formed in a plate material is used as an electronic component carrier tape. The guide edge is formed in a plane parallel to the feeding direction of the electronic component carrier tape, and is inclined at the front side of the plate material and close to the slit. And a relative position and inclination angle of the guide edge with respect to the slit after the cover tape is folded back along one of the two edges of the slit on the upstream side of the feed of the electronic component carrier tape. The above-mentioned feeding method when the tip of the cover tape when folded back further upstream along the edge is viewed from a direction perpendicular to the plane containing the electronic component carrier tape. It was chosen so that it would extend parallel to the direction and in the opposite direction.

Operation and Effect of Second Means In this way, like the first aspect of the invention, the jamming of the carrier tape is avoided by preventing the electronic component from being caught in the edge of the slit, and of course the cover can be avoided. Winding the cover tape on the carrier tape supply side because the tip of the tape extends in a direction parallel to and opposite to the feeding direction of the carrier tape when viewed from a direction perpendicular to the plane containing the electronic component carrier tape. Is possible. In other words, when the width of the cover tape peeling device is narrowed and a plurality of them are arranged in the width direction of the carrier tape, the installation space can be made small. Since the work can be performed without hindrance, the replacement work can be performed easily and quickly.

Embodiment Hereinafter, first, an embodiment of the second invention will be described in detail with reference to the drawings.

FIG. 1 shows an apparatus for supplying a plurality of types of chips in the order of mounting in order to mount a chip-shaped electronic component (hereinafter, simply referred to as a chip) having no lead wire on a printed circuit board.

A reel 18 around which a carrier tape (only a specific carrier tape 16 is shown) holding one type of chip is wound is rotatably mounted on a support roller 20 in each cartridge 10. The carrier tape 16 pulled out from the reel 18 is intermittently fed by a constant amount by an intermittent feeding device 22, and the cover tape peeling and winding device 2
After the cover tape is peeled off by 4, the unit length portion of the carrier tape body having one chip accommodating portion is held by the chip holding portion 14 of the pallet 12, and the held unit length portion is cut by the cutting device. It is cut by 26.
Then, the chip is directly taken out from the carrier tape main body of the unit length conveyed by the pallet 12 by the chip mounting device and mounted on the printed circuit board.

The pallet 12 is provided with a large number of chip holding parts 14 in a line, and is intermittently sent by an amount corresponding to one pitch of the chip holding parts 14, but since it is not directly related to the present invention, a detailed description will be given. Is omitted. Further, the cutting device 26 cuts the carrier tape main body between the fixed blade 28 and the movable blade 30, but this is not directly related to the present invention, so a detailed description thereof will be omitted. The device 22 and the cover tape peeling / winding device 24 will be described in detail.

The intermittent feeding device 22 includes a fixed guide 34 fixed to a block 32 forming a part of the cartridge 10. A guide groove 36 having a U-shaped cross section that opens upward is formed in the fixed guide 34, and the carrier tape 16 pulled out from the reel 18 serves as the fixed guide 34 and a movable guide 38 that closes the opening of the guide groove 36. It is guided and fed in the longitudinal direction from the right side to the left side in FIG. In the following description, in order to facilitate understanding, the upstream side (the right side in FIG. 1) of feeding the carrier tape 16 is simply referred to as the upstream side, and the downstream side (the left side in FIG. 1).
Is simply referred to as the downstream side.

As shown in FIGS. 2 and 3, the carrier tape 16 is a cardboard in which a rectangular electronic component housing hole 44 and a circular feed engaging hole 46 are formed at equal intervals along the longitudinal direction. Covering the tape 48 and the electronic component housing hole 44, the housing hole 4
It is composed of a thin and transparent upper cover tape 52 and a lower cover tape 54 which prevent the chip 50 housed in the housing 4 from coming off the housing hole 44. Cardboard tape 4
In the state where the lower cover tape 54 is attached to 8, the electronic component housing hole 44 becomes a bottomed electronic component housing recess.
As is clear from this, in this embodiment, the cardboard tape 48 and the lower cover tape 54 bonded together constitute the carrier tape body, and the upper cover tape 5
2 forms a cover tape that closes the opening of the electronic component accommodating recess.

As shown in FIG. 4, in the carrier tape 16, engagement projections 58 projecting from the outer peripheral surface of the sprocket 56 at equal angular intervals are engaged with the feed engagement holes 46, and the sprocket 56 is sprocket 56. Is intermittently fed by being intermittently rotated by an angle corresponding to one pitch of the protrusion 58. A gear 60 is coaxially fixed to the sprocket 56,
The sprocket 56 and the gear 60 are rotatably attached to a shaft 62. A pair of arms 64 are also rotatably attached to the shaft 62, and a pawl 68 is rotatably attached to the arms 64 by a shaft 66 as shown in FIG. The pawl 68 is biased by a torsion spring 70 in a direction to mesh with the gear 60, and the shape of the pawl 68 is such that when the arm 64 is rotated counterclockwise in FIG.
Is rotated in the same direction, and when the arm 64 is rotated in the clockwise direction, the gear 64 is passed over the tooth of the gear 60 and is engaged with the next tooth. Further, a locking member 72 is provided to prevent the gear 60 from being rotated clockwise by the frictional force between the claw 68 and the gear 60 when the arm 64 is rotated clockwise. The locking member 72 is movably held in a linear direction by a guide member 74 fixed to the block 32, and is biased in a direction to engage with the gear 60 by a coil spring 76, so that the tip end is gentle. The combination of the inclined surface and the steeply inclined surface allows the gear 60 to rotate in the counterclockwise direction but not in the clockwise direction. Further, the locking member 72 accurately determines the stop position of the sprocket 56 by accurately determining the stop position of the gear 60, and the carrier tape 16 (correctly, the carrier tape body after the upper cover tape 52 is peeled off). Also serves to prevent movement in the feed direction when the cutter is cut by the cutting device 26.

One end of a rod 80 is connected to the arm 64 by a pin 78, and the other end of the rod 80 is loosely inserted into a through hole formed in a guide plate 82 fixed to the block 32. A relay pin 84 is arranged below the rod 80,
It is held by a bracket 86 so as to be movable in the axial direction. The relay pin 84 has an action plate 9 fixed to the swing plate 88 when the swing plate 88 disposed therebelow is rotated counterclockwise in FIG. 1 by the drive shaft 90.
It is pushed up by 2, and pushes up the rod 80 to rotate the arm 64 counterclockwise. A moving member 96 that is moved in a direction perpendicular to the relay pin 84 by a solenoid 94 is engaged with an intermediate portion of the relay pin 84, and the relay pin 84 is always shown by a chain double-dashed line in FIG. As shown in FIG. 1, the solenoid 94 is held in a position where it does not come into contact with the working plate 92, but when the solenoid 94 is excited, the working plate 92 and the rod 80 are brought into a vertical posture as shown by the solid line in FIG. It intervenes between the two and serves to relay the driving force of the drive shaft 90 to the rod 80. When the relay pin 84 is in the state shown by the chain double-dashed line, the arm 64 is rotated clockwise by the urging force of the coil spring 98 and the stepped surface 100 of the rod 80 is rotated.
Is in contact with the guide plate 82 and is stopped,
The rod 80 reciprocates between the lowered position and the raised position shown in FIG. 1 to give the sprocket 56 intermittent rotation by a constant angle.

Next, the cover tape peeling and winding device 24 will be described.
This device 24 peels the upper cover tape 52 from the carrier tape 16 and winds it on a take-up reel, and comprises the movable guide 38 and a take-up device 102 described later. As shown in FIGS. 5 and 6, the movable guide 38 includes a support arm 104 and a movable guide body 106 fixed to the lower surface of the support arm with bolts, and one end of the support arm 104 in the longitudinal direction. Although it is rotatably supported by a shaft 105 in the section, the support arm 1 is always provided.
It is fixed to the fixed guide 34 by a screw member 107 attached to the other end of 04. Movable guide body 10
6 is housed in a thick plate 108 fixed in a state of being partially in contact with the lower surface of the support arm 104, and a recess 110 formed in an upstream side (right side in FIG. 6) of the lower surface of the thick plate 108. And a thin plate 112 to be fixed.
Is fixed to the support arm 104 such that the lower surface of the thin plate 112 and the lower surface of the thin plate 112 are flush with each other, and the thin plate 112 and part of the thick plate 108 cover the upstream side and the downstream side of the opening of the guide groove 36, respectively. It has become. Further, a notch 114 is formed in the thick plate 108 so as to cross the guide groove 36 from the side opposite to the side supported by the support arm 104.
The notch 114 has an upstream edge 116 which is substantially perpendicular to the feeding direction of the carrier tape 16, and a downstream edge 118 which is inclined at an angle of approximately 45 ° toward the upstream side. It has a letter shape, and the recess 110 is formed on the upstream side of the notch 114. On the other hand, the thin plate 11
The downstream edge 120 of the thin plate 112 is provided substantially in parallel with the downstream edge 118 of the notch 114 with a small distance, whereby the downstream edge 1 of the thin plate 112 is formed.
A slit 122 that is inclined at an angle of about 45 ° with respect to the feeding direction of the carrier tape 16 is formed between the groove 20 and the downstream edge 118 of the notch 114. Then, the upper cover tape 52 peeled off from the carrier tape 16 guided and fed by the fixed guide 34 and the thin plate 112 is pulled out from the slit 122 to the front side of the thin plate 112. As is clear from FIG. 5, the slit 122 has a slightly larger gap in the opening on the downstream side than the depth on the upstream side.

In addition, the end portion on the downstream side is notched on the upper surface of the thick plate 108.
A tape guide 124 that extends above 14 is fixed. The downstream edge 12 of the tape guide 124
6 is provided in a state of being inclined at an angle of about 45 ° in the direction opposite to the slit 122 with respect to the feeding direction of the carrier tape 16, and the upper cover tape 52 pulled out from the slit 122 to the front side of the thin plate 112 is a slit. After being folded back in a direction substantially perpendicular to the feeding direction of the carrier tape 16 at a downstream side edge 120 of the thin plate 112 which is an upstream side edge of 122, the tape guide 124 further moves to an upstream side at a substantially right angle at an edge 126. As shown in FIG. 7, when folded back, when viewed from above, the tip end side of the carrier tape 16 is pulled out in a direction parallel to the feeding direction of the carrier tape 16. Then, the winding device 1 is provided on the front end side thus pulled out in the opposite direction to the carrier tape 16.
It is adapted to be wound on the body 130 of the take-up reel 128 by 02. The carrier tape main body after the upper cover tape 52 is peeled from the carrier tape 16 is guided by the fixed guide 34 and the thick plate 108 and is sent to the downstream side. Further, as is clear from the above description, in this embodiment, the movable guide body 106 composed of the thick plate 108 and the thin plate 112 is a plate material, and the downstream end edge 126 of the tape guide 124 is a guide edge. is doing.

As shown in FIG. 1, the take-up reel 128 of the take-up device 102 is rotatable around the center line of the body 130 by the shaft 134 at the upper end of the column 132 fixed to the cartridge 10. It is supported. The shaft 134 is the eighth
As is clear from the figure, the column 132 and the block 1
It is rotatably stretched between the auxiliary column 138 fixed via 36 and the take-up reel 128.
It is attached via a one-way clutch 140.
The one-way clutch 140 is mounted in a direction in which rotation of the shaft 134 in the upper cover tape winding direction is transmitted to the winding reel 128, but rotation in the opposite direction is not transmitted. A lever 142 is fixed to an end portion of the shaft 134 protruding from the support column 132, and a connecting rod 144 is rotatable by a pin 146 at a free end portion of the lever 142 as shown in FIG. It is connected. On the other hand, another lever 14 is attached to the block 32 of the cartridge 10.
8 is rotatably attached by a shaft 150,
A yoke portion 152 formed at one end of the lever 148 is engaged with a pin 154 provided upright in the intermediate portion of the rod 80. Two levers 148 are provided in parallel with each other, and their ends on the side opposite to the side engaged with the pin 154 are fixed to each other by a pin 156 as shown in FIG. There is. This pin 156
Is a long hole 158 formed at the lower end of the connecting rod 144.
The pin 156 and the connecting rod 1.
A coil spring 162 is stretched with a preload between it and a pin 160 which is provided upright in the middle of 44. Therefore, the pin 156 is always engaged with the upper end of the elongated hole 158. However, when the take-up reel 128 is taken up by the upward movement of the rod 80 while keeping this engaged state, Take-up reel body 130
The amount of movement of the outer peripheral surface of the
The ratio of the lever 148 and the lever 142 is selected so as to be larger than the amount by which the carrier tape 16 is intermittently fed. That is, the amount of the upper cover tape 52 that can be wound by one rotation of the take-up reel 128 is set to be larger than the feed amount of the carrier tape 16.

As shown in FIG. 1, a plate spring 164 is cantilevered by a bolt 166 on a block 136 fixed to the support column 132, and the free end of the plate spring 164 is fixed to the take-up reel 128. It is in contact with the outer peripheral surface. The tip end of an adjusting screw 168 screwed into the block 136 is brought into contact with the middle portion of the leaf spring 164, and the amount of protrusion of the adjusting screw 168 from the block 136 is adjusted so that the leaf spring 164 and the leaf spring 164. The frictional force with the take-up reel 128 is adjusted.

A detection arm 170 is further provided near the block 136.
Is provided. As is apparent from FIG. 8, the detection arm 170 is rotatably attached to the outer surface of the column 132 by a shaft 172, and the detection pin 17 is provided at one end thereof.
4 are erected. Although the detection arm 170 extends to both sides from the portion supported by the shaft 172, the detection pin 1
The side on which 74 is erected is slightly longer and therefore tends to rotate counterclockwise in FIG. However, normally, the detection pin 174 is in the position shown by the solid line in FIG. 1 by engaging the upper cover tape 52, and when the upper cover tape 52 loses tension due to breakage or the like, the detection arm 170 is reversed. It is designed to rotate clockwise. The operator uses this detection arm 170
It is known that the upper cover tape 52 is broken by the counterclockwise rotation. The rotation of the detection arm 170 is detected by a photoelectric switch or the like, and the upper cover tape 5
It is also possible to electrically notify the breakage of No. 2 by an alarm device or the like.

Next, the operation will be described.

In the non-operating state, the oscillating plate 88 is in a lower rightward state than the state shown in FIG. 1, the relay pin 84 is in a state shown by a two-dot chain line, and the rod 80 is in a lowering position.
Therefore, the lever 148 is in a position rotated counterclockwise by a certain angle from the state shown in FIG. 1, and the connecting rod 144 is in a position higher than the position shown in FIG.

In this state, the pallet 12 is fed by one pitch, and one of the many chip holding portions 14 is stopped at a position facing the tip of the fixed guide 34. When the chip holding portion 14 should not receive the chip 50 held by the carrier tape 16, the solenoid 94 is not excited and the relay pin 84 is maintained at the position shown by the chain double-dashed line. Therefore, even if the oscillating plate 88 is rotated to the position shown in FIG. 1 along with the rotation of the drive shaft 90, the action plate 92 does not contact the relay pin 84 and the intermittent feeding device 22 does not operate. Also, the cover tape peeling and winding device 24 does not operate.

However, when the chip holding portion 14 stopped opposite to the fixed guide 34 is to receive the chip 50 held by the carrier tape 16, the solenoid 9
4 is excited, and the posture of the relay pin 84 becomes vertical. Therefore, if the drive shaft 90 and the swing plate 88 rotate counterclockwise in this state, the action plate 92 contacts the lower end of the relay pin 84 and pushes it up. Relay pin 8 pushed up
4 abuts on the lower end of the rod 80 and pushes it up to rotate the arm 64 counterclockwise against the biasing force of the coil spring 98. As a result, the claw 68 causes the gear 60
Is rotated by a certain angle, and the sprocket 4
2 rotates to feed the carrier tape 16 by one pitch.

At the same time that the intermittent feeding device 22 operates, the cover tape peeling and winding device 24 also operates. That is, the upward movement of the rod 80 causes the lever 148, the connecting rod 144, and the lever 14 to move.
2, it is transmitted to the take-up reel 128 via the shaft 134 and the one-way clutch 140, and it is rotated. By the rotation of the take-up reel 128, the upper cover tape 52 is peeled from the carrier tape 16 being fed by the intermittent feeding device 22 as described above, and the peeled upper cover tape 52 is cut from the slit 122 to the front side of the thin plate 112. And is taken up by the take-up reel 128. At that time, the upper cover tape 52 is attached to the downstream edge 1 of the thin plate 112.
The carrier tape 16 is folded back at a substantially right angle to the carrier tape 16 at 20 and then the downstream edge 126 of the tape guide 124.
As described above, it is further folded back at a substantially right angle and is pulled out in the direction opposite to the carrier tape 16. The amount of the upper cover tape 52 that can be wound by one intermittent rotation of the take-up reel 128 is set to be larger than the intermittent feeding amount of the carrier tape 16 by the intermittent feeding device 22 as described above. However, when the feed amount of the intermittent feeding device 22 exceeds the feed amount, the pin 156 is actually the coil spring 1.
The upper cover tape 52 is absorbed by moving downward in the elongated hole 158 against the urging force of the upper cover tape 52.
Does not break. Further, as the winding diameter of the upper cover tape 52 on the take-up reel 128 increases, it is necessary to reduce the actual intermittent rotation amount of the take-up reel 128.
This change in the rotation angle is also automatically adjusted by the extension of the coil spring 162.

After the carrier tape 16 is intermittently fed by one pitch and the upper cover tape 52 is wound as described above, the drive shaft 90 and the swing plate 88 are rotated clockwise, and the relay pin 84 and The rod 80 descends and the claw 68
Rotates together with the arm 64, gets over the teeth of the gear 60, and is ready to engage with the next tooth. Also, the lever 148
Is also rotated counterclockwise, and first the coil spring 1
The extension of 62 is canceled and the pin 156 engages with the upper end of the elongated hole 158. After that, the connecting rod 144 is raised with the rotation of the lever 148. As a result, the lever 142
Although the shaft 134 is rotated in the clockwise direction in FIG. 1 via the, the one-way clutch 140 does not transmit the rotation in this direction, so the take-up reel 128 does not reverse.

As is clear from the above description, in this embodiment,
Intermittent feeding device 22 and cover tape peeling and winding device 24
The cover tape peeling device for the carrier tape 16 is constituted by the above.

By the way, in the cover tape peeling device of this type, conventionally, a slit for drawing the cover tape to the front side of the movable guide is formed at a right angle to the feeding direction of the carrier tape. The carrier tape is lifted by the vibration caused when the cover tape is lifted together with the cover tape or peeled off from the carrier tape body, and further caused by the operation of each part of the device, and is caught on the downstream edge of the slit. There was a case where the jamming occurred between the edge of the slit and the carrier tape due to the feeding of the cover tape, and jamming for preventing the pulling out of the cover tape and the feeding of the carrier tape occurred. The upper cover tape 52 to the movable guide 38 (strictly speaking, a thin plate Since the slit 122 for pulling on the front side of the 12) are formed inclined with respect to the feeding direction of the carrier tape 16, chip 50 is slit 1
The downstream edge 1 of the notch 114, which is the downstream edge of 22.
It is not caught on 18, and therefore jamming does not occur. That is, in the device of this embodiment,
As shown in FIG. 5, as the carrier tape 16 is fed, the corner portion A of the downstream end of the chip 50, further on the inner side of the slit 122, first faces the slit 122, and thereafter, The portion facing the slit 122 gradually moves toward the corner B of the diagonal position of the corner A, but when the corner A faces the slit 122, the chip 50 is upward in the diagonally long portion. Since the cover tape 52 suppresses the protrusion from the electronic component accommodating concave portion, even if the force for lifting the chip 50 from the electronic component accommodating concave portion acts, the corner portion A is almost lifted from the electronic component accommodating concave portion. Therefore, the corner A has a downstream edge 118 of the notch 114.
It is not possible to cause jamming by being caught in. Further, after that, when the upper cover tape 52 is peeled off from the carrier tape body, the effect of the upper cover tape 52 to prevent the chip 50 from rising from the electronic component accommodating concave portion is gradually reduced, so that the chip 50 is notched. It becomes possible to float up to the lower end position of the edge 118 on the downstream side of 114, but at this time, since the corner portion A of the chip 50 has already passed through the slit 122 and has entered the lower side of the thick plate 108, its floating Thick board 10
It is prevented by abutting on the lower surface of 8. That is,
Also at this time, the tip 50 is not caught by the downstream edge 116 of the notch 114, and therefore jamming is not caused.

The embodiment of the second invention of the present application has been described above. However, this is a literal example, and the invention of the present application should not be construed as being limited to the above specific example.

For example, in the above-described embodiment, the movable guide main body 106 as a plate member is composed of the thick plate 108 and the thin plate 112, but the movable guide main body 106 may be integrally formed by one member, and the tape guide may be used. Similarly, 124 can be integrally formed with the thick plate 108 and the thin plate 112.

Further, in the above-described embodiment, the carrier tape main body after the upper cover tape 52 is peeled off is further guided by the fixed guide 34 and the thick plate 108 and sent to the downstream side, and the cutting device 26 stores one electronic component. The concave portion is cut and moved to the chip holding portion 14 of the pallet 12, and the movement of the chip holding portion 14 conveys it to the chip mounting device. The part of the thick plate 108 that guides the movable guide main body 106 is formed of a member different from that of the movable guide main body 106. While preventing the floating, it guides the carrier tape body, and when the carrier tape body is stopped, the electronic component accommodating concave portion on the fixed guide 34 It is retracted from the fixed guide 34
It is also possible to directly extract the chip 50 from the upper electronic component accommodating recess by a chip mounting device. In this case, the movable guide body 1
06 and the separate member separated from the movable guide body 106 constitute a plate member.

Further, in the above-described embodiment, the inclination of the slit 122 and the downstream edge 126 as the guide edge of the tape guide 124 is substantially 45 ° opposite to the feed direction of the carrier tape 16, and the slit 122 The upper cover tape 52 drawn from the thin plate 112 to the front side of the thin plate 112 is folded back substantially at right angles at the downstream edge 120 of the thin plate 112 and the downstream edge 126 of the tape guide 124. The tape 16 was guided in the direction opposite to the feeding direction and wound around the take-up reel 128 provided above the cartridge 10, but these slits 122 (strictly speaking, the upstream edge thereof). Edge 1 on the downstream side of the thin plate 112
20) and the inclination angle of the edge 126 of the tape guide 124 with respect to the feeding direction of the carrier tape 16 does not need to be substantially 45 °, respectively, and other combinations of angles can be used to fix the upper cover tape 52. The carrier tape 16 can be guided in a direction opposite to the feeding direction so that the carrier tape 16 can be wound around the winding reel 128. In short, the upstream edge 120 of the slit 122 and the downstream edge 126 of the tape guide 124 are the upper cover tape 5 and
If 2 is folded back by each of them, the tip side thereof is selected so as to extend in a direction parallel to and opposite to the feeding direction of the carrier tape 16 when viewed from the direction perpendicular to the surface containing the carrier tape 16. , Cartridge 10
The take-up reel 128 provided above the device can take up the film, and the widthwise dimension of the device can be narrowed. However, the upstream edge 1 of the slit 122
The extending direction of the upper cover tape 52 after being folded back at 20 differs depending on the inclination angle of the edge 120 of the upper cover tape 52 with respect to the feeding direction of the carrier tape 16. In order to fold the tape 16 in the direction opposite to the feeding direction, it is necessary to adjust the position of the downstream edge 126 of the tape guide 124 as a guide edge in the feeding direction of the carrier tape 16.

It is to be noted that the embodiment in which the tape guide 124 is provided and the upper cover tape 52 is not bent in the direction opposite to the feeding direction of the carrier tape 16 is the embodiment of the first invention of the present application. The tape 52 cannot be pulled out in a direction parallel to the feeding direction of the carrier tape 16 when viewed from a direction perpendicular to the surface containing the carrier tape 16, but it can prevent the chip 50 from being caught by the edge of the slit 122.

Furthermore, it is possible to employ a carrier tape feeding device, a winding device, and the like having a structure other than that of the above embodiment.

Although not listed one by one, it goes without saying that the invention of the present application can be implemented in various modified and improved modes without departing from the spirit of the invention.
